1️⃣ 📊💸 NLP and generative models for psychology research — Thomas Wood¶

Harmony (harmonydata.ac.uk) is a free online tool that uses generative AI and LLMs to help psychologists analyse datasets.

It uses Python, Pandas and HuggingFace Sentence Transformers to find similarities between questionnaires.

Psychologists and social scientists often have to match items in different questionnaires, such as "I often feel anxious" and "Feeling nervous, anxious or afraid". This is called harmonisation- a time consuming and subjective process. Going through long PDFs of questionnaires and putting the questions into Excel is no fun!

We've been working on an open source Python library and free web tool called Harmony which uses natural language processing and generative AI models to help researchers harmonise questionnaire items, even in different languages. https://pypi.org/project/harmonydata/ https://github.com/harmonydata/harmony

2️⃣ 🛠️🌐 Homomorphic Encryption in Python - Sefik Ilkin Serengil¶

Discover the power of homomorphic encryption in Python with a focus on secure cloud computing!

Learn how calculations on encrypted data can be performed in the cloud without exposing the private key.

We'll showcase LightPHE, a lightweight Python library that supports various homomorphic encryption schemes, and walk through an end-to-end example. Uncover the practical applications of homomorphic encryption and its potential to transform data privacy in the cloud.
